ATTACHMENT FOR LOCO'MOTIVES.

Application filed August 8, 1921, Serial No. 490,605. Renewed Getober 21, 1926.

it i vention relates to improve- .nienis in attachments tor locomotives, and more i'iarticularly refers to an improveddevice fior effectively luhricating` the cylinders ot a locomotive, and at the saine time servii to break the vacuum in the cylinders v. Ythe locomotive drifting or coasting unir ythe throttle closed.

Y No small trouble andannoyance has been cxperieinet lenetotfme4 in rthe proper lubrication oi the internal parts. ot locomotive cjfliulers and tau ty lubrication has resulted in the trefnoce sity 'tor renewing' piston rings, removingl carbon, and otherwise repairing the pistons and scored cylinder walls. i'loreover, it is desirable to insure the 'llow ol lubricant not only when the engine is operating' under seain, but also when drifting' or coasting with the throttle closed.

Y lt i-a anjobject ot the present invention to accomplish the accurate and timely lubrication of loceinclive cylinders by a device which will at the saine time operate to relieve the vacuum which the traveling` pistons tend to lcreate in the cylinders when the engine ccas'sting' or drifting. and which willv furthermore serve to furnish lubricant to the internal parts whenever the locomotive motion without regard to whether it u or movingl under steam.

i Another ohject oi? the invention is to proviili` a device for caluying` out the above deihcl purposes in a simple yet faithful mannen and wherein the device is of a simple and inexpensive structure and is so huilt n be capable et installation upon s et present types n'ie'hout any alteration therein.

."i still Afurther object et' the invention is to provid:x means :2.o that steam will cushion the steam pisfons and their reciprocating parts in the steam c vliud rs and keep the sniper-heated units inoi i while the locomotive is coasting ordrit'ting. Y

"il'ith the l'nfegfoingr and other objects in viewvn the invention will be more .tully described hereinafter, and will be more particularly pointed out in the claims appended hereto,

Fig. S) is a diagrammatic view showing` the device in connection with a lubricant chest.

Referring' more particularly to the drawand for the present to Figs. l to 8 in` elusive.Y l designates a shell or casing,` having an internal barrel 2 centrally therein and with its axis disposed vertically and surrounded hy an annular chamber 3 ot' substantially `great capacity which has a threaded nipple e extending from the lower portion thereot at one side to connect, as by n'ieans ot a coupling' nut 5, with a pipe section (l which receives steam trom the steam dome or other suitable source ot supply.

the lower portion ot the barrel 2 diainctricalljv :diningI periorations 7 and 8 are Vmade to put the steam pipe 6 and the annular chamher 3 in communication with a pas- 'e 9 which extends downwardly at one de ot the shell l and communicates at its lo part. with a conduit 10 made in a coupling; head ll. which is bolted or otherwise secured to the botfomot the shell l. The couplingl head 1l also carries an extension 12 adapted to receive a-suitable coupling for placing the passage 9 and the conduit 10 in communication with a similar apparatus which situated at the other side of the locomotive and acts in conjunction with the cylinder and steam chest at that side.

The devices may, however, be entirely independent, in which case the extension 12 nililv lle ilispeneeil ivii'll or llliigireil. .lfn ille lower eeni `:il poriioii ol ille shell Ai hellellili ille lialrrel 2 :lnil eollziiiil i'herelviill il: il` evlinilei' 12' nl nil ellllirgeiil (lizinleier :ley eoni pzirecl iliih ille llore ol ille hill-rel :.3 unil hui'- iup; :i pinion il illerein reeipvoeziiinf;` vel-iirillllv :nul :lillip'ieljl io lliziell'. when ill ille upper poniiioii. :l peri` lil in ille liilile \vlill ol ille :"iliinllill .lll u'hiell einllnlunieiliellA iviih ille pliuezilre .l. ln il. siliiilzir will', :iiiie loivei.' pouiiion un nlleivn in Fie'.

whichis disposed ust above the locomotive cylinder nidicated d]agrammatically at GG andinia/'ing the petcock G7 to which the downwardly by gravity. The oil passages 32 and 33 are shown as passing substantially horizontally through the shell 1.

In the operation of the device the oil flows fromvv the lubricator 71 to the drifting de- This reservoir 71 is the usual oil res'- ervoir 'found on all locomotives and the-oil is subjected in the customary way to a lsteam two hundred pressure lof approximately the oil down pounds, the steam driving through the drifting device.

During the runningof the locomotive with the throttle open the parts are in the position shown in Figure 2 so that the port- 31 registers with the passages 32 and 83 and forms a through way for the oil from theV lubricator to the pipeV 69 which connects with the steamsupply pipe 68 to the locomotive steam chest 65. llVhen the throttle is open. ,and the locomotiveinemotion, ther steam chest pressure gets `up beneath the lower piston 14 and moves vthe parts upfr vwardlyto theeXtent shown infFigure 2.

In this it is assisted by the saturated .steam lpressure getting Vfrom the central chamber 3 through theports 43 to the under sid-e of the larger 'pistone 27. In this-position the lubricant is Vfed at all times to theV locomotive parts yas -iust explained. 'Moreover the piston 14 in the upper position exposes the port16 to the steam pressure', the :steam passing upjthrough the lpassage 17 as shown in Figure 8 and raising the non-return check valve 20. This permits steamto accumulate in the dome or chamber 19 above the upper larg-er piston 27. In the upper position Aof the parts, the upper piston 27, as shown in Figure 2,will `mask the outlet port "28 and prevent the evacuation ot this accumulated pressure 'in thev dome por upper Furthermore thesolid portion ot the stem will obstructvia tl rough. passage past the ports 7 and 8l and will cut off communication between the central chamber 3 and the passage 9.

Assoon as Athe throttle is closed and the locomotive begins to dritt7 the pressure beneath the lower piston 14 at once falls and the accumulated pressureA in the dome or upper chamber- 19V becomes effective to drive chamber 19.

the pistons down to the position shown in Figure 8. rlhe annular groove B5 in the stem registers with the ports 7 and 8 and satu- 'rated steam, which is received in the chamber 3 from the boiler, is permitted access toV the passage' 9 and to the steam chestsand (Flinders ol 'the ltr-emotive. Through the connections 1() and 12 the saturated steam is supplied to the valve chests at both sides oic the locomotive and this saturated steam breaks the vacuum, meistens the Vparts and keeps the same heated.

In the low-er position of the parts the vupperport L11 of the stem 29 lregisters with the oilppassage 32 and receives oil from the 'lubricatorf71, introducing oil to .the bore 30 ot thestem 29.V VThe oil driven down by two hundred' pounds steam pressure from the lubricator 71 is forced out ot the ports 31 at the base ot the stem. rlhese ports are numerous as indicated in Figure 8 and are small'in diameter vand they form a choke.

The oil gets out through the port 15 and mixes immediately,with the saturated steam by which it is carried to the Vlocomotive parts. Y y

' Then the locomotive is slowing to a stop the slow movement of the locomotive pistons makes it impossible tor the parts to use up the saturated steam being delivered to the same and consequently a back pressure occurs beneath the `lower piston 14traising the parts again to the position shown in Figure 2, it 'being understood that the accumulated pressure in the upper 'chamber 19 has i escaped throughthe port 28 to the atmos- Cit phere during the previous lower position Vot the piston 27. 'This back pressure isotf course evacuated u when .the-locomotiveA is brought toay complete .stop andthe saturated steam pressure from th'eucentral chamber 3,Ah'zwingr accessbeneath `the `upper larger pistoni 27 willhold the parts in .the raised position.` f y `l/Vhat -is claimed is: f Y A l, 1n attachment for locomotives com- Lprisinga casing having cylinders therein in communication at their outer ends with the steam chest pressure of the locomotive,
